I am starting Business studies this fall and and an an mature student I am worried about my math knowledge since I havnt studied it for a time. I am also an international student and thus dont have the same school system as in the UK so its a bit confusing as to what math would be sufficient to brush up on. Is studying old GSCE exams good enough or do I also need to look into A-levels math? GSCE is pretty much what I did in my first year of highschool, but since the course dosnt have A-levels math requirement I assume this wont be needed to start the course?
